NOTE
The capacity is shared equally between all partitions.
This is done by assigning each partition getCapacity() / partitionCount
available slots in the event journal. Because of this, the effective total
capacity may be somewhat lower and you must make sure that the
configured capacity is at least greater than the partition count.

Time to live can be disabled by setting timeToLiveSeconds to 0. This means that the events never expire but they can be overwritten when the capacity of the journal is exceeded.
